FIG. 1 is a perspective view of patterning tool showing my new design;

FIG. 2 is a left side view thereof;

FIG. 3 is a top view thereof;

FIG. 4 is a front view thereof; and,

FIG. 5 is a reference perspective view for illustrating the manner of use thereof with the scribing device shown in broken lines.
